OIL BURNER.

Application filed February This invention relates to oil burners and has for its object the provision of a simple burner which may be easily placed within the fire-b0): of an ordinary furnace and operated economically and without the noises incident to the use of many oil burners now upon the market. The invention seeks to provide aburner which may be easily assembled and which will be so constructed that the oil will be thoroughly vaporized and will be commingled with air so as to produce an intense flame of wide spread which will burn without depositing any carbon, and the invention also seeks to provide a burner in which,

" when installed, all the air flowing thereto will be directed to the points where it will meet the vaporized oil in such manner that a thorough commingling of the vapor and the air will be effected and perfect combustion result. These stated objects, and other objects which will incidentally appear in the course of the following description, are attained in such a device as is illustrated in the accompanying drawings and the invention resides in certain novel features which will be particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a vertical section of a burner embodying my invention as installed within the fire-box of a furnace;

Fig. 2 is a plan view of the burner with the burner plates removed;

Fig. 3 is a top plan view of the burner plates;

Fig. 4 is a bottom plan view of the lower burner plate, and

Fig. 5 is an enlarged detail section on the line 5-5 of Fig. 2.

In the drawing, the reference numeral 1 indicates a portion of the shell of a furnace, and 2 the usual grate installed in said shell and constituting the bottom of the ire-box.

In carrying out my invention, 1 provide a base plate 3 which may be of any conven-v ient form and is illustrated in Fig. 2 as sub-- stantially elliptical to facilitate its insertion through the ordinary fuel door of the furnace. This base plate is provided with a depending marginal rim 4: adapted to rest upon the grate 2 in spaced relation to the shell 1 and thereby provide an outer chamber which receives cement or other plastic material, indicated at 5, so that there can be 19, 1925. Serial No. 10,401.

only a restricted circulation of air through the furnace around the base plate and near 1y all air entering the ash pit or the space below the grate 2 will be directed into the chamber defined by the depending rim 1. The central portion of the base plate is depressed or beveled inwardly and downward- 1y, as indicated at 6, so as to provide a ring or flange having a central opening constituting a passage for the air flowing thereto through the grate 2. The central opening is seen most clearly at 7 in Fig. 2, and it will be noted that the available portion of the central opening takes the form of a relatively narrow arcuate slot, the inner wall of which is defined by an annular plate or spider 8 having radially extending lugs or arms 9 projecting at intervals from its edge under the ring 6 and preferably formed integral with the latter. The annular plate or ring 8 is formed in its upper face or top side with concentric grooves 10 and 11, the outer one of which, 10, is adapted to receive and hold a wick 12 of asbestos or similar material whereby oil delivered into the inner groove 11 will be confined to said groove and will not be permitted to overflow the ring onto the grate and be lost or constitute Oil is supplied to the groove a fire menace. 11 through an auxiliary feed pipe 13 which has its end threaded into a nipple 14% on the under side of the spider or circular plate atany convenient point thereof, the bore 15 of said nipple or boss opening through the bottom of the groove 11, as seen most clearly in Fig. 5.

The annular plate 8 which constitutes an ignition pan also furnishes a support for the burner plates, the lower burner plate 16 being circular in plan view and being provided on its under side with spaced lugs 17 and 18 which are adapted to rest upon the edge of the circular plate 8 at the inner sideor' the groove 11, as shown in Fig. 1. As will be understood upon reference to Figs. 1 and 4:, the lugs 1'? and 18 are formed to define shoulders 19 which will engage the edge of the annular plate 8 and thereby maintain the concentric relation of said plate and the burner plate, and the lugs 17 are provided at their inner sides with threaded sockets 20 to receive securing screws or bolts 21 which are inserted upwardly through a clamping bar 22 into the said sockets, as

shown clearly in Fig. 1, whereby the burner plate will be secured firmly in place, it being understood that the ends of the clamping bar bear against the under side of the annular plate or ignition pan 8. Upon reference to Fig. 2, it will be noted that the bar 22 is relatively narrow so that there is an open space through the central portion of the plate 8 and at the sides of the clamping bar for the circulation of air. The oil supply pipe 23 may be carried into the furnace from a distant point of supply through the ash pit of the furnace or through an opening provided especially therefor in the shell of the furnace, but in any event it is provided at its inner end with a vertical delivery branch passing upwardly through the grate 2 and through a central opening of the clamping bar 22 to engage a central opening in the burner plate 16, the end of said branch and the burner plate being provided with external and internal threads whereby the pipe may be firmly secured in the plate. Referring particularly to F1 1, it will be noted that the lower burner plate is constructed with a central conical portion 96 so that the oil escaping from the pipe i l will flow outwardly and downwardly and tend to collect in the annular channel 27 formed in the plate at the base of the conical portion The outer wall of this channel is formed by a circular rib 28 upon the upper sine of. the burner plate at the edge thereof and of less height than the central conical portion At intervals upon the edge of the burner plate are lugs 29 which consitute spacers to hold the lower burner plate 16 and thupper burner plate 30 out of contact and thereby provide a passage through which the vaporized oil may escape. The upper burner plate 30 has a cross sectional forin conforming to the lover plate and presents a central conical portion 31 which is of greater diameter than the conical portion so and also of greater height than the I d portion 26 whereby a considerable space Y .i occur between the two burner plates. as shown in Fig. 1. At the base of the conical portion 31, the upper burner plate has a short annular web 32 extending substantiah ly parallel witn the floor of the channel 27 in the lower burner plate'and is then formed with an annular substantially if-shaped 33 fitting over the rim or rib 28. Tee on web of the rib 83 extends downwardly and outwardly and converges slightly toward the edge of the lower burner plate so that the inner surface of this wall will rest upon the lugs 29, as shown in 1. From the lower edge of this outer wall of the rib 33, there extends a circular marginal portion 34:. the radius of which is nearly equal to the radius of the ring 6 below it. This web or plate 34-. extents upwardly and outwardly roni the lower edge of the rib 33, as clearly shown in Fig. 1, and is substantially parallel to the upper surface of the ring 6 so that a passage is provided for the air {luv-ling through the slot 7 and through the space below the lower burner plate. The slot 7 is located radially beyond the lugs 29 and the space defined by said lugs so that the air rising through the slot will mingle with the vapor at a point beyond its point of emission from the burner plates. the greater body of air passing iuawardly from the center of the ignition pan or plate 8 and flowing laterally from below the lower burner plate. Disposed concentrically about the upper burner plate is a silencer consisting of a l'llll or ring resting upon the grate 2 and a perforated plate 86 extending inwardly from and carried by its upper edge, an inner ring 38 being between and concentric with the rim l and the ring The space between the ring 38 and the rim 4 is sealed with the cement 5 but an open air passage 39 is left between the rings 35 and It will be noted. that the upper burner plate is not lined to the silencer nor to the lower burner plate but simply rests upon the lugs 29 on the lower burner plate. This manner of supporting the upper burner plate facilitates its removal in the event that cleaning or inspection of the device necessary. and to aid removal or replacement a ring or eye 3? is formed on the plate at its center. which eye or ring may be easily engaged by any Iorin or. withdrawing tool or may be simply lifted by hand. All the parts may 1e made in niating halves to facilitate insertion through the fuel door of the furnace.

When the burner is to be used, a s s cient quantity of oil to fill the groove 11 is permitted to flow into said groove through the branch supply pipe 3, the flow being cut off when the oil reaches the top of the wick 12. This initial supply of fuel is ignited, and it will make a flame suflicient to heat the burner plates and effect initial vaporization of any fuel which may be permitted to flow through the supply pipes 23 and When the initial supply of fuel in the groove 11 has been consumed, the flow of fuel through the pipes 23 and El is permitted, and this fuel will overflow down the conical portion 26 of the lower burner plate and eventually escape through the space bet veen the burner plates and the lugs 25). is the Vapor issues from the said space. it will be ignited and the flame and the heat therefrom. will then rise through the perforations of the plate 36 and act upon the walls of the furnace firebox to heat the same in the same manner that a coal tire ordinarily would perform that work. Experience has deinonstrattul that by supplying the air to the vapor in the manner shown and described through the space below the burner plate and also through the slots 7, thorough coinniingling of the air and the oil vapor is effected, and this vapor will be completely consumed without any deposit of carbon upon any of the parts of the device. Moreover, by interposing the perforated silencer plate 36 around the burner and confining the flame and heat so that it can escape only through the perforations of said plates, I have eliminated the exceedingly disagreeable noise which is incidental to the use of most oil burners now upon the market. My device is exceedingly simple in the construction and arrangement of its parts, may be easily as sembled and installed in any furnace and may be operated very economically.
